Centaurus A: Galaxy on Collision (Picture of the Day)

Centaurus A
Centaurus A (NGC 5128) is one of the closest radio galaxies to Earth, which is in the constellation of Centaurus. It is about 10-16 million light years away. This galaxy is the fifth brightest in the sky. There  has been a debate of whether this is an elliptical galaxy or lenticular galaxy, but now with the help of the Spitzer Space telescope, it is discovered that it is going through a galaxy collision.
